Oblicz masę tlenu zawartego w pomieszczeniu w wymiarach 4m x 5m x 10m wiedząc że gętość tlenu wynosi 1,43g/dm3
V=d/m
V=4m*5m*10m=200m3
V=d/m ?*m
d=V*m / /V
m=d/V
m=0,00143g/m3 / 200m3=0,00000715g
V = 4mx5mx10m= 200 m3
d= 1,43 g / dm3
v = 200m3 =200 000 dm3
m = d * v = 1,43g/dm3 * 200 000 dm3 = 286 000 g = 286 kg
wzór na d to d = m/v
